Overview
The Simrad 000-14974-001 is a WM-4 installation kit with mounting hardware and an SMA adapter that connects the WM-4 antenna to the WM-4 Satellite Interface.
This is the small set of parts you reach for during a new WM-4 install, a module swap, or a refit where the original antenna adapter or fasteners are missing. It keeps the antenna connection correct at the receiver side and helps secure the WM-4 components so they stay put when the boat is moving.
Key features
- Made for Simrad WM-4 Sirius satellite weather systems
- SMA adapter for the WM-4 antenna connection to the WM-4 Satellite Interface
- Includes mounting hardware used during WM-4 installation and service work
- Useful for clean re-installs after console work, electronics upgrades, or troubleshooting
What’s included
- SMA adapter for the WM-4 antenna connection
- Mounting screws and hardware
Compatibility and fit
This kit is specific to the WM-4 system and the way the WM-4 antenna connects to the WM-4 Satellite Interface. If your boat uses a different Sirius receiver or a different antenna connector style, this is unlikely to be the right adapter.
Installation and setup
Support the antenna lead so the SMA connection is not carrying the weight of the cable run. Keep bends gentle and avoid routing where the cable can be stepped on, pinched by a hatch, or tugged when you pull electronics out for service.
Start SMA threads by hand to avoid cross-threading, then snug the connection. Placing the connection inside a dry console or electronics compartment helps reduce intermittent issues caused by moisture and vibration.
Who this is for
This kit makes sense for boaters running a WM-4 receiver who are installing the system for the first time or putting one back together after a dash rebuild. It is also a practical fix when the original WM-4 antenna adapter or mounting screws have gone missing during service.
